Abstract
The utility model discloses a lubrication structure which can be used for an in line multi-cylinder fuel injection pump used ejector-body component. Lubricating oil channels which are directly communicated to a roller pin are symmetrically opened on the inside of the ejector-body and lubricating oil can enter into a lubricating oil film which is formed between a roller and the roller pin from the upper end of the ejector-body through the lubricating oil channels. The contact state of a kinematic pair is changed, the anti-wear ability is greatly increased, and simultaneously the carrying capacity is also increased.
Description
Technical field
The utility model belongs to a kind of parts of diesel injection pump, particularly a kind of in-line multi-cylinder Injection Pump lubricating structure of tappet body.
Background technique
Along with the development of diesel technology, for Economy and the emission performance that improves diesel engine, fuel-injected ultrahigh pressureization is the inevitable development direction of fuel oil supply system, and this need increase substantially the pump end pressure of Injection Pump.Along with the raising of pump end pressure, bearing capacity is had higher requirement, this produces CR Critical mechanical wear fault to kinematic pair to cause in the Injection Pump roller and roller pin, has a strong impact on the life-span of Injection Pump.And existing Injection Pump does not have corresponding lubricating structure with the tappet body component.
The model utility content
The purpose of this utility model: realize lubricating between roller and the roller pin, this does not easily produce mechanical wear to kinematic pair because of there being lubricating structure to cause roller and roller pin with the tappet body component to solve existing Injection Pump, thereby the problem of mechanical failure takes place, the lubricating structure of a kind of Injection Pump with the tappet body is provided, can the effectively lubricating roller and roller pin this to kinematic pair, reduce its mechanical wear, improve the working life of roller and roller pin, thereby prolong the working life of Injection Pump.
The purpose of this utility model realizes by following technical proposals:
A kind of Injection Pump lubricating structure of tappet body, the inboard symmetry of described tappet body offers first oil leab that leads to roller pin, offer second oil leab that communicates with first oil leab on the roller pin, on the inboard that the other end opening of second oil leab is located at roller pin and the face that roller contacts.
The other end opening of described first oil leab is positioned at a following position of tappet body upper end dress piston spring.Make lubricant oil reach second oil leab that communicates with it through first oil leab from a following position of tappet body upper end dress piston spring, flow out from the inboard that is positioned at roller pin and the opening on the roller surface of contact of second oil leab, between the surface of contact of roller pin and roller, form lubricant film, to reduce the mechanical wear of both surface of contact.
Described first oil leab, second oil leab are two groups, and symmetry is opened in the both sides of roller, and the opening that is positioned at the roller pin inner side surface of two group of second oil leab communicates.Set up two groups of oil ducts, can make lubricant oil enter surface of contact between roller and the roller pin simultaneously from the both sides of roller, accelerate flowing and evenly distributing of lubricant oil, strengthen lubrication effect.
The utility model adopts offering oil leab on the tappet body and communicates with oil leab on the roller pin, and the oil leab outlet of roller pin is opened on the face that roller pin is inboard with roller contacts, can make lubricant oil enter into surface of contact between roller and the roller pin by above-mentioned oil duct, form lubricant film, strengthened roller and roller pin this to the lubrication effect of kinematic pair in movement process, reduced the mechanical wear that both cause because of motion, improve the working life of roller and roller pin, thereby also correspondingly prolonged the working life of Injection Pump.The utility model is applicable to the Injection Pump of the diesel engine lubrication effect of strengthening on the tappet body between roller and the roller pin.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Number in the figure, the 1st, the tappet body, the 2nd, roller, the 3rd, roller pin, the 4th, tappet body inner top side, the 5th, the inboard of roller, 6 is first oil leabs, 7 is second oil leabs.
Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
The lubricating structure of Injection Pump usefulness tappet body as shown in Figure 1, tappet body inner top side at tappet body 1 offers two groups of first oil leabs 6 that are symmetrical in tappet body 1 vertical center line downwards, offers second oil leab 7 that also communicates with it corresponding to first oil leab 6 on roller pin 3.The centre of two group of second oil leab 7 communicates and is opened on the face that roller pin 3 is inboard with roller 2 contacts.
The filler opening of first oil leab 6 is positioned at a following position of tappet body upper end dress piston spring.
During use, lubricant oil enters first oil leab 6 from a following position of tappet body upper end dress piston spring, the flow through vertical part of second oil leab 7, be positioned at the opening outflow of roller pin 3 middle inside again to second oil leab 7, between the inboard surface of contact of the inboard 5 of roller and roller pin 3, form lubricant film then, with improve roller pin and roller this to kinematic pair lubrication effect in movement process, reduce its mechanical wear, prolong its working life.
